Problem

After the upgrade to the Cisco Unified Communication Manager 5.x, the Corporate Directory does not work. With Cisco CallManager 5.x, when the IP phone dials from the Corporate Directory and the Corporate Directory is configured to dial with a plus sign, the call fails with a fast busy tone.

Solutions

In order to resolve the issue, try either of these solutions.

Solution 1: Directory Lookup Dial Rule

Logon to the Cisco CallManager Administration page.

1. Go to Call Routing > Directory Lookup Dial Rule.

2. Add a new rule with Number Begins With that includes the plus sign '+' and Total Digits to be Removed that includes a plus sign, as well.

   

   Save the new Directory Lookup Dial Rule, and test if it works correctly.

   

Solution 2

If the call fails when the phone dials a number with a non-dialable character, such as - ( ) [], the IP phone firmware cannot support non-dialable characters. In order to resolve this issue, you must upgrade the IP phone firmware or edit the Directory Dial Rule so that non-dialable characters do not appear.
